Refining pedotransfer functions for estimating peat bulk density [PDF]
Mires and Peat, 2017 Several previous studies have demonstrated the close relationship between peat dry bulk density and gravimetric moisture content. However, the basis for including peat ash (mineral) content or variation in the specific gravity of peat solids has not been

Considering the soil compaction status on logging areas in a Hyrcanian forest
Journal of Forest Science, 2015 This paper deals with the issue of soil compaction during timber harvesting operations on cutting areas. Soil compaction was assessed following the logging operation in Darabkola forest area by measuring soil bulk density.

Density: Bulk in-situ or SG? [PDF]
Journal of the Southern African Institute of Mining and Metallurgy, 2021 The density used to covert volume to tons is critical in determining the real in-situ tonnage of Mineral Resources. However, the methods used to determine density and the use of different technical terms are seen to be inconsistent throughout the industry.

Soil displacement and soil bulk density changes as affected by tire size [PDF]
, 2013 The selection of the appropriate tire size and inflation pressure for a particular load and soil condition is a critical consideration to ensure that the effects of vehicle traffic on soil compaction are minimized and that agricultural soils are managed ...

Bulk Density Adjustment of Resin-Based Equivalent Material for Geomechanical Model Test
Advances in Materials Science and Engineering, 2015 An equivalent material is of significance to the simulation of prototype rock in geomechanical model test. Researchers attempt to ensure that the bulk density of equivalent material is equal to that of prototype rock.

The formation bulk density prediction for intact and fractured siliciclastic rocks
Geodesy and Geodynamics, 2019 The formation bulk density is one of the most important rock properties required for reservoir evaluation and geomechanical analysis. In intervals where the formation bulk density logs are not acquired, the industry practice is to estimate the formation ...

Optical Properties of Neutral F Centers in Bulk MgO with Density Matrix Embedding
, 2023 The optical spectra of neutral oxygen vacancies ($F^0$ centers) in the bulk MgO lattice was investigated using density matrix embedding theory. The impurity Hamiltonian was solved with the complete active space self-consistent field (CAS-DMET) and second-

Modeling the Impact of Rhizosphere Bulk Density and Mucilage Gradients on Root Water Uptake
Frontiers in Agronomy, 2021 In models of water flow in soil and roots, differences in the soil hydraulic properties of the rhizosphere and the bulk soil are usually neglected. There is, however, strong experimental evidence that rhizosphere and bulk soil hydraulic properties differ
